Bought this in 2014 to have a track day car to drive to the events and as a hobby car to work on. Car has AC, cruise control, Bluetooth, Torsen LSD, Toyota COP ignition, 70mm Mustang TB., BRP Supercharger (MP62) at 12.5 PSI (120mm Crank Pulley, 65mm Snout.) Makes about 200 WHP. Track wheels are Motegi 15x8, currently shod with 205/50R-15 Bridgestone Potenza RE-71RS SL w/ 4-5/32nds. Street wheels are ’99 OEM fat fives with Yokahama S-Drives with next to no miles, stored in bags inside but with 2018 date codes. Oil filter changed yearly and oil changed once or twice a year. I’ve put 22k miles on the car. Car has approx. 124,000 miles on it. Asking $10,500.

Fenders are rolled. Driver side front fender is replacement due a spin after the car in front of me dropped a coolant hose at the bottom of the down hill at Lime Rock. Spray painted the replacement, as you can see in the pictures. This is a track-day car, not a show car. :-) All wheel well rust repaired but notice a small outside bubble in the pic of the driver's side rear tire.

Full set of new Hawk HP Plus Sport/Track pads, front and rear, not installed. Present pads have 5-6mm on them. Redline 75W90 differential gear oil - 2022

Have following OEM parts: Seats (driver side foamectomied,) power steering rack, hood, trunklid (with camera port.) Softtop removed and converted to Project-G G-String Bikini Top. Also have Stormproof Car Cover by Coverking - 12-22-20 but car garaged since 2022. All lights and windows work. Recently replaced the power window switches.

Issues – There is a small oil pan leak. A week after a track day, there will be a couple of drops on the floor. The rear brake calipers are Autozone remans and the e-brake does not self-adjust. Small rust bubbling in front of driver’s side rear wheel. Coated the area inside the wheel well with Por-15.

The pic with the Tirerack windshield banner was from an SCCA time trial that I did a while back. All other driving events were HPDE.























Selling because I'm getting old. Ordinarily that wouldn't change things but this year I developed arthritis in my hip so getting in and out of a lowered Miata with race seats has turned into a hassle.

 

Here's the current ECU set up.
